As Fernando Pessoa would say: "working with nobility, sincerely waiting, feeling the people with tenderness, this is the true philosophy" and it is in her that my being resides, the here being giving the best of me and waiting for the best of you.

Estudio clínico-epidemiológico de la infección por Bordetella pertussis en la isla de Gran Canaria en el período 2008-2016

Pacientes y métodos: Se revisaron retrospectivamente las historias clínicas de los pacientes con diagnóstico microbiológico de infección por B. pertussis mediante reacción en cadena de la polimerasa, de enero de 2008 a diciembre de 2016. Resultados: Se identificaron 110 pacientes, de los cuales 105 (95,4%) fueron menores de 6 meses y el 59,1% eran varones. La incidencia anual de hospitalización se estimó entre 13,7 y 425,0 casos por cada 100.000 lactantes menores de 12 meses, con 2 picos en 2011 y 2015. Los familiares cercanos fueron las principales fuentes de contagio potenciales. Las principales manifestaciones fueron la tos pertusoide asociada con signos catarrales, cianosis y linfocitosis. El 15,4% de los pacientes presentaron complicaciones (principalmente neumonía), pero la evolución fue favorable en todos los casos. La menor edad y la no vacunación se asociaron con un mayor riesgo de desarrollar complicaciones (p < 0,05). La coinfección viral ocurrió en el 31,6% de los pacientes diagnosticados de infección por B. pertussis. Conclusiones: La incidencia de infección por B. pertussis ha aumentado en los últimos años en nuestra área, con un menor desarrollo de complicaciones y con tasas de mortalidad inferiores al período anterior. La menor edad y la no vacunación previa se consideran factores de riesgo para el desarrollo de complicaciones. La vacunación en mujeres embarazadas probablemente disminuirá la incidencia en el futuro, sobre todo en niños menores de 6 meses.

Primary cutaneous nocardiosis: a pitfall in the diagnosis of skin infection

Infection, 2017

present in three different forms: superficial infection, lymphocutaneous infection and mycetoma [... more present in three different forms: superficial infection, lymphocutaneous infection and mycetoma [2]. Primary cutaneous nocardiosis has been more frequently reported in immunocompetent individuals, opposed to the disseminated form that commonly occurs in immunocompromised hosts [1, 3, 4]. When a primary cutaneous infection is suspected, the skin biopsy is the most valuable sample. A history of gardening, farming, or contact with animals should raise suspicion for primary cutaneous nocardiosis. A 73-year-old male with no relevant past medical history presented with a painful lesion in left lower leg of 2 weeks’ duration (Fig. 1). The patient reported that the cutaneous lesions started as an erythema, which progressed in size and became tender. The patient denied contact with animals and travel history, but had been handling plants the previous weeks. He did not recall any trauma. A skin biopsy was performed. Following local antibiotic guidelines, empiric therapy for skin cellulitis with amoxicillin/ clavulanate 875/125 mg q8h for 2 weeks was prescribed. The histological analysis revealed an abscessified dermohypodermic inflammation suggestive of an infectious process (Fig. 2). Three weeks later filamentous Gram-positive rods compatible with Nocardia sp. were isolated in the culture media from the biopsy sample (Fig. 3). Nocardia brasiliensis was finally identified by ribosomal sequencing. The patient was diagnosed with primary cutaneous nocardiosis. After 1 year of follow-up the patient remains asymptomatic (Fig. 4). Nocardiosis is an infection caused by Nocardia sp. Skin lesions may occur secondarily and result from the dissemination of a systemic infection previously acquired by inhalation of rods, or through direct skin inoculation leading to primary cutaneous nocardiosis [1], which may
